Two shoots of the liverwort, Diplophyllum albicans, under the compound microscope at around x100 total magnification. They have dark reddish-brown stems and green leaves. There are small, black spots on some of the leaves along with tiny open networks of brown, anastomosing hyphae.
A ruptured black-brown fruitbody of Bryobroma caudatum with two hyaline, globose immature asci emerging from it. The fruitbody is sitting on a fragment of leaf tissue with mycelium on top of it. Image at x1000 magnification.
Some ellipsoidal, hyaline ascospores beside a ruptured fruitbody of the fungus. One with a tail is indicated by an arrow.
The mycelium of B. caudatum and related species is formed of conspicuous brown hyphae that mostly grow on top of the anticlines of the host cells, occasionally forming tiny pin haustoria that penetrate the cell walls (not easily visible unless sections are made). The host cells cytoplasm is intact and the underlying cells are living, with chloroplasts and oil bodies. Image at x1000 magnification.
Nice to find good material of a tiny fungus, Bryobroma caudatum, on the liverwort Diplophyllum albicans yesterday. The fungus produces tiny fruitbodies up to only 75 microns diam. and spores with little tails. The distinctive mycelium forms a network over the host cell walls without killing them.
